Intelligent motor vehicles, charging systems, and control logic for governing vehicle grid integration operations

Abstract

Presented are vehicle charging systems and control logic for provisioning vehicle grid integration (VGI) activities, methods for making / using such charging systems, and electric-drive vehicles with intelligent vehicle charging and VGI capabilities. A method of controlling charging operations of electric-drive vehicles includes a vehicle controller detecting if a vehicle is coupled to an electric vehicle supply equipment (EVSE), and determining if the vehicle's current mileage exceeds a calibrated mileage threshold. Responsive to the vehicle being connected to the EVSE and the vehicle's current mileage exceeding the calibrated mileage threshold, the controller determines the current remaining life of the vehicle's traction battery pack and the current time in service of the vehicle. The vehicle controller determines if the current remaining battery life exceeds a predicted remaining battery life corresponding to the current time in service. If so, the vehicle controller enables the traction battery pack to transmit electrical power to the EVSE.

Description

INTRODUCTION

[0001] The present disclosure relates generally to electrical systems for charging motor vehicles. More specifically, aspects of this disclosure relate to systems, methods, and devices for provisioning intelligent vehicle charging and vehicle grid integration activities.

[0002] Current production motor vehicles, such as the modern-day automobile, are originally equipped with a powertrain that operates to propel the vehicle and power the vehicle's onboard electronics. In automotive applications, for example, the vehicle powertrain is generally typified by a prime mover that delivers driving power through an automatic or manually shifted power transmission to the vehicle's final drive system (e.g., differential, axle shafts, road wheels, etc.). Automobiles have historically been powered by a reciprocating-piston type internal combustion engine (ICE) assembly due to its ready availability and relatively inexpensive cost, light weight, and overall efficiency. Such engines inclu...

Embodiment Construction

[0019]This disclosure is susceptible of embodiment in many different forms. Representative embodiments of the disclosure are shown in the drawings and will herein be described in detail with the understanding that these embodiments are provided as an exemplification of the disclosed principles, not limitations of the broad aspects of the disclosure. To that extent, elements and limitations that are described, for example, in the Abstract, Introduction, Summary, and Detailed Description sections, but not explicitly set forth in the claims, should not be incorporated into the claims, singly or collectively, by implication, inference or otherwise.

[0020]For purposes of the present detailed description, unless specifically disclaimed: the singular includes the plural and vice versa; the words “and” and “or” shall be both conjunctive and disjunctive; the words “any” and “all” shall both mean “any and all”; and the words “including,”“containing,”“comprising,”“having,” and the like, shall e...
